Myrrborg

Myrrborg was a Viking kingdom in Ireland which existed from 915 to 1173 AD, with the Irish port of Myrrborg (Cork) serving as its capital. It was founded by Norse settlers as a trading community, and the Norse settlers would become the forefathers of the Coppinger and Cotter families of present-day Cork. In 1173, Myrrborg sent an expedition of 32 ships to resist the Viking invasion of Ireland, but the fleet was defeated and Myrrborg conquered by England.
